Authors McCabe and Wolock (2011) write that “effects of global warming on streamflow magnitude are of particular concern given that these effects directly alter water supplies.” In this regard, however, they say that “previous studies of trends and variability of streamflow in the United States primarily have focused on the latter half of the 20th century,” noting that these trends “may not be representative of longer time periods.” Thus, they decided to significantly increase the time domain of their new study of the subject to cover the period 1900-2008, stating that it would “be informative to evaluate temporal patterns in streamflow over the longest possible period,” which is critically important, in light of the fact that Earth’s recovery from the global chill of the Little Ice Age began well over a century ago.
